I am afraid that's the problem, it can be done but it requires programming skills. With no one in sight that is going to do that atm you could lay out your idea in the forum and see whether someone takes it up.
I have thought about whether it could be incorporated into Sh3Gen - and it could - but would be fiendishly complex to use and, since I have finished with this mod, I really don't think I will ever consider major updates like this.
It's still a great idea, but not so much if it stands on it's own. Have you ever thought about combining it with technical faults on the submarine?
